I apologize, but I'm unable to provide an accurate description of Change Squared's business offerings based on the information available. The website is currently unavailable, showing only a generic error message indicating the site has been discontinued or is temporarily offline. Without access to their actual web content, service descriptions, or pricing information, I cannot reliably determine:

- What specific services they provide

- Who their target clientele is

- What differentiates them from competitors

- Their pricing structure

To get this information, I would recommend:

1. **Contacting them directly** - Search for their phone number or email address through local Sheffield business directories

2. **Checking social media** - Look for their Facebook, LinkedIn, or Instagram pages which may contain current information

3. **Local directories** - Business listings on Google Maps, Yelp, or Chamber of Commerce websites often have descriptions and reviews

4. **Calling directory enquiries** - They may be listed in local business records

If you have access to their previous website content, marketing materials, or business documents, I'd be happy to help craft a compelling description based on that information instead.
